You&rsquo;d think there would be some modules out there but I have not found anything. (This device could be made to work, but it would be overkill.)</p>
<p>Anybody found anything like that?</p>Customer #408359 on WRL-08952 - Bluetooth Breakout - Bluegiga WT-32Customer #408359urn:uuid:37b82946-9f88-6469-53e2-abf5184ae9fb2013-02-12T10:21:39-07:00<p>I need your help to choose the best suitable kit for my project, which is sending voice from a mobile phone via bluetooth to a Bluetooth kit which will forward this voice to another mobile phone (full duplex).</p>
<p>Thats mean the two mobiles will make aphone calls and the kit will act as the BTS (Base Transceiver Station)</p>
<p>Is this kit able to receive and send voice and make a piconet (connect to more than a device at a time)</p>rbrucemtl on WRL-08952 - Bluetooth Breakout - Bluegiga WT-32rbrucemtlurn:uuid:a796f34d-8df7-ed93-aec0-14f5f50104152013-02-04T04:40:53-07:00<p>It&rsquo;s not super complicated to update the firmware&hellip; login to bluegigas support site and you&rsquo;ll find everything you need.</p>mtrask on WRL-08952 - Bluetooth Breakout - Bluegiga WT-32mtraskurn:uuid:a487eb32-0d1c-7023-0523-327e2a16b1282013-01-14T14:04:38-07:00<p>Dudes - aren&rsquo;t you at least a little bit embarrassed that you&rsquo;re selling this (expensive) board with three-year old firmware in it? I&rsquo;m sorry about your inventory problem but I&rsquo;d think you could at least provide a procedure for updating since there&rsquo;s been two whole major releases since iWRAP 3.0.</p>FlippinJax on WRL-08952 - Bluetooth Breakout - Bluegiga WT-32FlippinJaxurn:uuid:3ef5f67c-0d4b-ac9e-a52b-4f46efb707c02012-09-26T21:34:46-06:00<p>Agreed. Why does the board cost $50 more than the part (on the Sparkfun site)?</p>thomasqbrady on WRL-08952 - Bluetooth Breakout - Bluegiga WT-32thomasqbradyurn:uuid:f94e0761-8f90-3a08-9a8c-368052deb1ab2012-09-13T10:58:17-06:00<p>8MHz users rejoice! I was able to get the WT32 to communicate with an Arduino Fio, which has an 8MHz processor, by first connecting to an Arduino Uno (you could also connect via USB to a PC). Once connected that way, I was able to communicate with the WT32 at its native 115200 baud rate (too fast for the Fio to keep up), and send the serial command to set the WT32&rsquo;s baud rate down to 9600 (SET CONTROL BAUD 9600,8n1).</p>
<p>Then I reconnected the Fio, and I&rsquo;m in business.</p>thomasqbrady on WRL-08952 - Bluetooth Breakout - Bluegiga WT-32thomasqbradyurn:uuid:1b4cf5b3-7c87-891f-ba2d-f4734b1b5f912012-08-31T09:59:37-06:00<p>Regarding 5idget&rsquo;s problem, and what I may be getting myself into, can you successfully use this board with an 8mhz Arduino? I have a Fio running at 3.3v / 8mhz. How do I set these up?</p>TheoS on WRL-08952 - Bluetooth Breakout - Bluegiga WT-32TheoSurn:uuid:38492908-ea48-c233-e41d-43ef5941a7102012-08-22T17:18:16-06:00<p>I had an interesting experience I thought I would share. I attached one of these to an ATMega328P running at 3.3V with an 8Mhz external oscillator, and uploaded some simple code to send it the AT command and listen back for &ldquo;OK&rdquo;. It sent the command just fine, but would spit back gibberish as the response from the board, almost as though I was listening on the wrong baud rate. After messing with it for a couple days, I finally hooked it up to an UNO, and it worked perfectly. That led me to switch out the 8Mhz oscillator on my original setup to a 16Mhz. 100% communication now. Thought I would share this in case anyone else encounters similar issues: use a 16Mhz oscillator!</p>cdv123cdv on WRL-08952 - Bluetooth Breakout - Bluegiga WT-32cdv123cdvurn:uuid:1da1cd27-4828-7c60-dcf5-19809eac71a82012-03-09T09:47:01-07:00<p>$33 for WT32 on Mouser, $90 for breakout on Sparkfun. $57 for breakout board???</p>Customer #155117 on WRL-08952 - Bluetooth Breakout - Bluegiga WT-32Customer #155117urn:uuid:a73de343-3128-52b0-f186-fa5ac8a9f2552012-02-28T09:27:39-07:00<p>I&rsquo;m looking at putting a bluetooth module inline between a headset and intercom.

The WT32 has an internal battery charger connected to VDDbat which I though was pretty cool, but since it&rsquo;s connected with VDDio it&rsquo;s rendered unusable.</p>speck on WRL-08952 - Bluetooth Breakout - Bluegiga WT-32speckurn:uuid:32f591ad-0c0f-71ed-94b8-791b833d33f12010-09-17T07:12:24-06:00<p>I just noticed that I was blind as the last line on the web page states<br/>

Does this breakout board come with the module or must the module be ordered separately from the breakout board? If the breakout board comes with the module, is the module also soldered into place?<br/>

i2s (or even pcm spdif) is what sets this apart and you guys omitted it. so sad ;(<br/>
can you add it for the next rev?<br/>
I know of a few DACs (good ones, cheap) that take i2s as input. this could be a very nice product IF you support digital audio on break-out pins.</p>Innovations on WRL-08952 - Bluetooth Breakout - Bluegiga WT-32Innovationsurn:uuid:a24eabe5-b48f-abc1-5b5b-828e1a66761b2010-07-20T17:09:08-06:00<p>This looks like a great dev item and a great bluetooth module.<br/>
Is there any added value in purchasing the dev kit made by BlueGiga?

Bluegiga have released V4.0.0 (<a href="http://www.bluegiga.com/show_news?id=17348332" rel="nofollow" >http://www.bluegiga.com/show_news?id=17348332</a>), which fixes this problem, as well as adding a bunch of new features. They let me have the new firmware and a PC application to upgrade the firmware on my WT-32 via a serial port (I actually used Sparkfun&rsquo;s XBee Explorer USB as a simple USB-to-3.3V-serial converter).<br/>
For most applications, V3.x is probably fine, but if you&rsquo;re using HID (that&rsquo;s all I&rsquo;ve tried), you need V4. Sparkfun might want to consider getting V4 modules in the future.</p>SnOwen on WRL-08952 - Bluetooth Breakout - Bluegiga WT-32SnOwenurn:uuid:082bb06b-370f-acc5-e968-49d6a3ac16362010-01-15T17:01:54-07:00<p>I got one of these in September last year (2009), and the firmware was V3.0.0, which <em>isn&rsquo;t</em> Beta. Bluegiga have a V3.1.0 firmware which <em>is</em> Beta &ndash; I programmed it via a serial port from a PC with a software tool they supplied, but V3.0.0 seems pretty reliable.<br/>
Since the thing that sets the WT32 apart from other Bluetooth devices is its audio capabilities, it&rsquo;s a shame that this board doesn&rsquo;t break out the digital PCM audio pins for connection to a processor or stand-alone ADC/DAC (it <em>does</em> break out the analog audio in/out).</p>Oleg on WRL-08952 - Bluetooth Breakout - Bluegiga WT-32Olegurn:uuid:6976b0cf-0b32-8dbb-798a-382870fd745d2009-11-23T21:23:32-07:00<p>wow! you are carring it now! do you still send a free one for suggesting?</p>jescombe on WRL-08952 - Bluetooth Breakout - Bluegiga WT-32jescombeurn:uuid:1cf5c9b0-7b78-4c4f-7eb7-62a7e1bbc0362009-02-11T05:14:21-07:00<p>Just fyi - these have a beta firmware revision (which is missing some functions like a2dp volume control).<br/>
It&rsquo;s possible to upgrade by making a parallel-spi interface cable (schematics and PC software are on the bluegiga site), and it <em>might</em> be possible to upgrade over UART (but this failed for me).</p>
